Running a 32bit application on a 64bit Access

[CD Tom]

I have a guy that has Access 64bit installed on his computer and is using it with another application. When he tries to run my app it reinstalls the runtime 32bit access, then when he runs his other app it reinstalls back to the 64bit. When we try and run my application in the 64bit version is gives us a message the my app was created in a 32bit version and will not open. Is there any way to get my application to work with Access 64bit? I've tried changing the accdr to an accde but that doesn't help.

Thanks again for all your help.

My understanding is that the 32bit and 64bit versions of Access just do not mix at all. That is why I have Office installed as a 32bit application on my 64bit machine.

That's what I have done also but this guy didn't do that and now we're having problems.

Microsoft recommends that the 32bit version of Office be installed for most users because of this issue.

There is only one workaround at this point, to un-install the 64bit version and install the 32Bit.

Sorry there isn't a better solution for your client.

Can I run a 32bit Access runtime and a 64bit Access at the same time? When I run my 32Bit Access program it works fine but when we try and start the 64Bit access program it installs the 64Bit access, and then when we run the 32Bit program it installs the 32bit runtime again.

I believe that's already been answered Tom. If it isn't clear then "No. You can't". Running both versions together will continue to give you problems.

Some people use VMs to ensure the two systems are kept separate.

Sorry, I didn't go back and check previous. I'm just wishing something could be done.

I feel your frustration. It's a horribly messy area TBF.

The best idea I've come across so far is the one about running them in separate VMs.

For the very stout of heart, there is information out there about how to make your code flexible between versions, but even then I couldn't guarantee you'd be able to run both systems in parallel.
